The invention discloses a combined energy absorption type anti-creeper for a rail vehicle, which belongs to the technical field of rail locomotives and comprises an inner pipe, an outer pipe and an energy absorption aluminum honeycomb, and a plurality of guide grooves are formed in the side wall of the inner pipe. A mounting plate is arranged at one end of the outer pipe, a plurality of guide pin assemblies are fixedly embedded in the mounting plate, a plurality of guide pins extend out of the guide pin assemblies, the guide pins are arranged in the corresponding guide grooves, and the guide pins are in interference fit with the guide grooves. And the energy-absorbing aluminum honeycomb is clamped between the inner pipe and the outer pipe. The guide pin is in interference fit with the guide groove, so that the anti-creeper has two combined energy absorption modes of crushing energy absorption of the energy absorption aluminum honeycomb and extrusion deformation energy absorption of the guide groove, and the anti-creeper has the advantages of light weight, high energy absorption capacity and the like. And meanwhile, the structure of the guide pin and the guide groove reduces the play gap between the outer pipe and the inner pipe, so that the anti-creeper has excellent guide performance in the working crushing process, and the stability of the anti-creeper during crushing during train collision is improved.
本发明公开了一种轨道车辆用组合吸能式防爬器,属于轨道机车技术领域,包括内管、外管以及吸能铝蜂窝,内管的侧壁上设置有若干导向槽。外管的一端设置有安装板,安装板内嵌固有若干导向销组装,导向销组装上延伸出若干导向销,若干导向销布置于对应导向槽内,导向销与导向槽过盈配合。吸能铝蜂窝夹持于内管与外管之间。导向销与导向槽的过盈配合,使得防爬器拥有吸能铝蜂窝压溃吸能和导向槽挤压变形吸能两种组合吸能方式,让该防爬器具有重量轻、吸能量大等优点。同时,导向销和导向槽的结构减小了外管与内管之间的窜动间隙,让防爬器在工作压溃过程中具有优良的导向性能,提高了列车碰撞时防爬器压溃时的稳定性。
